William Wordsworth, a visitor to Barmouth in the 19th century, described it thus: "With a fine sea view in front, the mountains behind, the glorious estuary running eight miles [13 km] inland, and Cadair Idris within compass of a day's walk, Barmouth can always hold its own against any rival."[This quote needs a citation]

Dinas Oleu (Citadel of Light), which is located east of the town on the adjoining hillside,[1] was the first tract of land to be donated to the National Trust.[5]

In January 2014, two trains were stranded at Barmouth after severe winter storms destroyed the sea wall at nearby Llanaber.[6]

Barmouth is the venue for the annual Barmouth Beach Race, a motocross event. Usually taking place on the last weekend in October, the event sees riders take part in beach racing, using a temporary motocross course constructed on the beach. Over 200 riders typically take part in this event, with spectators attending free of charge. The event attracts champion riders from England and Wales.[9]
